Thank you, Marttila and Ivan, As the original author of prettyNum() {etc ..}, I will commit such a bug fix to R-devel (and probably port it to R 4.5.0 patched) quite soon (but not yet today).

Dear list, I'd like to report a bug in `prettyNum()`. When called with a numeric vector, the `replace.zero` argument is disregarded. > prettyNum(0, zero.print = "- ", replace.zero = TRUE) [1] "-" Warning message: In .format.zeros(x, zero.print, replace = replace.zero) : 'zero.print' is truncated to fit into formatted zeros; consider 'replace=TRUE' A

Dear list, Have I stumbled upon a bug, or am I holding `prettyNum()` wrong? Please see below. Best, Mikko > prettyNum(0, zero.print = "- ", replace.zero = TRUE) [1] "-" Warning message: In .format.zeros(x, zero.print, replace = replace.zero) : 'zero.print' is truncated to fit into formatted zeros; consider 'replace=TRUE' > prettyNum(0, zero.print =

Thanks for the contribution Mikko! For testing future patches, you can actually do it right in the web browser, thanks to Heather Turner's R Dev Container, see instructions here https://contributor.r-project.org/r-dev-env/container_setup/ Best Toby On Mon, May 26, 2025 at 6:28?PM Martin Maechler <maechler at stat.math.ethz.ch> wrote: > Thank you, Marttila and Ivan, > > As

Hi, Dear R-help I know there are some R package to deal with zero-inflated count data. But I am now looking for R package to deal with zero-inflated continuous data. The response variable (Y) in my dataset contains a larger mount of zero and the Non-zero response are quite right skewed. Now what i am doing is first to use a logistic regression on covariates (X) to estimate the probability of Y

...do, I hope the nbd maintainer on > qemu side can explain this. qemu-img tries to efficiently zero out the whole device at once so that it doesn't have to use individual small write requests for unallocated parts of the image later on. The problem is that the NBD block driver has max_pwrite_zeroes = 32 MB, so it's not that efficient after all. I'm not sure if there is a real reason for this, but Eric should know. > However, since you suggest that we could use "trim" request for these > requests, it means that these requests are advisory (since trim is), and > we c...

Folks, If I have a vector such as the following: x <- c(0, -1, -1, -1, 0, 0, 1, -1, 1, 0) and I want to replace the zeroes by the nearest non-zero number to the left, is there a more elegant way to do this than the following loop? y <- x for (i in 2 : length(x)) { if (y[i] == 0) { y[i] <- y[i - 1] } } > y [1] 0 -1 -1 -1 -1 -1 1 -1 1 1 You can see the first zero is left as is, the next...

Add coverage for the previous patch. Although most plugins don't change can_fua or can_fast_zero on the fly, the code should still not abort when calling .zero with a flag that was permitted by the previous open but not permitted by the current open.

Hello Imagine I have a vector with ones and zeroes I write it compactly: 1111111100001111111111110000000001111111111100101 I need to get a new vector replacing the "N" ones following the zeroes to new zeroes. For example for N = 3 1111111100001111111111110000000001111111111100101 becomes 11111111000000011111111100000000000011111111000...

Hi, I recently updated to R 3.0.1. I'm running linux ubuntu 12.04. I realized that I have to update all the installed packages so I run > update.packages(checkBuilt=TRUE) as described here http://www.r-bloggers.com/r-3-0-0-is-released-whats-new-and-how-to-upgrade/ . The first thing it did was telling me that it will not update several packages. When it was finished I used the warnings

This is going to be true whether or not you write zeroes in 32M chunks or in 2G chunks - it takes a long time to write actual zeroes to a block device if you are unsure of whether the device already contains zeroes. There is more overhead for sending 64 requests of 32M each than 1 request for 2G, there's a question for whether that's in the noise...

Hi everyone, I have a matrix that has a combination of zeros and NAs. When I perform certain calculations on the matrix, the zeros generate "Inf" values. Is there a way to either convert the zeros in the matrix to NAs, or only perform the calculations if not zero (i.e. like using something similar to an !all(is.na() construct)? Thanks, rcoder -- View this message in context:

...en small negative results are truncated back to zero in standard precision. The following snippet handles the signedness in fusedMultiplyAdd: /* If two numbers add (exactly) to zero, IEEE 754 decrees it is a positive zero unless rounding to minus infinity, except that adding two like-signed zeroes gives that zero. */ if (category == fcZero && sign != addend.sign) sign = (rounding_mode == rmTowardNegative); The test "category == fcZero" tells us that the result was zero after rounding back down to standard precision, but since the addition is carried out in extended prec...

Hello, everyone, There's a problem about zero in R and I really need your help. I have a vector shown as x=c(0.1819711,0.4811463,0.1935151,0.1433675), The sum of this vector is shown as 1 in R, but when I type 1-sum(x), the value is not zero, but -2.220446e-16. I can accept that this value is quite small and could be seen as zero, but there would be a problem when it's not really
